Hindu God Varaha, Vishnu Avatar - The Boar

The third avatar, Varaha, was
taken at the end of the last flood in the Satyuga, when Bhoomi Devi
(Earth Mother) sank to the bottom of the ocean. A demon
Hiranyaksha, had prayed for Lord Brahma and got awarded a boon that
no beast nor man nor god could kill him. But somehow from the list
of beasts the name of boar was missing. This proved to be his
lacunae. He then started a campaign of plunder across the worlds. He
pushed the world to the Pataal loka, or the under of the sea. He
stole the Vedas, the Holy Scriptures from the Lord Brahma, while he
was asleep and performed huge atrocities. To retrieve the Vedas and
to save the world the Lord Vishnu assumed the role of a boar and
brought out the earth from the under of the ocean, using its two
tusks. It then killed Hiranyaksha and retrieved the Vedas from the
asura and brought it back to the safe custody of the Lord Brahma.
